Top Tips To Stop Mould Around Windows

Many homes, particularly older homes, are prone to getting mould around windows. This can cause damage to window frames, especially timber ones, and cause health problems. Whilst the mould certainly doesn’t look nice, it’s not the biggest problem. Living with mould in your house can lead to health problems.

Why Does Mould Grow Around Windows?

Mould is a fungus which can grow on almost any surface where moisture is present. The spores are present in the air and when they meet with moisture they grow and multiply. The biggest cause of mould around windows is condensation. The warm air inside the home hits the glass of the window where it is rapidly cooled by the outside air producing condensation.

Other factors which increase condensation are:

Wet and humid weather

Insufficient heating

Leaking pipes

The steam caused by a bath or shower

Smoking

Open fires and wood burners

Why Is It A Health Problem?

Mould exposure causes a variety of health problems, mostly respiratory.

Symptoms include:

Nasal and sinus congestion

Runny nose and sneezing

Eye irritation

Wheezing and problems breathing

Tight chest and coughing

Throat irritation

Rashes

Headaches

How Can Mould Be Removed?

Due to the health problems it can cause, it is important that mould is regularly removed. There are a variety of ways you can do this depending on whereabouts of the mould.

The Best Way To Remove Mould From Around Windows Is Bleach

Wear rubber gloves and make sure that the window is open so that there is plenty of ventilation. Be careful not to get bleach on any paint, carpet or fabric as it will cause damage.

Mix one part bleach to three parts warm water in a bowl

Use a non-abrasive brush to clean off the mould

Regularly dip the brush in the bowl and thoroughly clean the whole area

Dry the cleaned surface with a cloth

Leave the window open until completely dry

There are lots of other sprays and cleaning detergents which can get rid of mould, but they don’t always remove the black staining. Some of these detergents can also damage the seal around double glazing, therefore, it is wise to approach with caution. The best way to deal with mould around windows is to prevent it from growing in the first place. There are a few different ways you can tackle this.

How Can You Prevent It From Growing?

Mould is caused by condensation. Condensation is created by excess moisture, therefore, the best way to prevent it is to remove as much moisture as you can.

Opening Windows In The Bathroom And Turning On The Extractor Fan

Making sure than any steam created in your bathroom leaves via a window or extractor. This is important whilst the shower or bath is running and afterwards until the steam has gone. Wiping down wet surfaces once you have finished will also help.

Dehumidifier

Dehumidifiers are a great way of removing excess moisture in the air. They come in a variety of different sizes and price-points. Check out This Guide to find the best one for you. Keeping your home heated evenly and not allowing the temperature to dramatically rise and fall will help prevent condensation. If warm air quickly becomes cold and then warm again it will produce moisture, causing condensation.

Double Glazed Windows

The reason that mould is so common around windows is that the warm air from inside meets the cold air from outside. The best way to stop this is by creating an insulating layer between the cold outside and warm inside. Good quality double or triple glazed windows do exactly that. Specifically designed to prevent heat passing from the inside to outside and vice versa. This means that the surface of the inner pane remains warm, creating significantly less condensation and therefore mould.

Prevention Is Better Than Cure
